FLEXIBLE TUBULAR CLAMIING JACKET.

Application filed January 10, 1921. Serial No. 436,401. 7

To all. whom it may concern:

Be it known that I. RIcnAnn D. KNIGHT, a citizen of the Ihiited States,and resident of the city of Providence, in the county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Flexible Tubular Clampin ets, of which the. following is a specication.

This invention relates to a flexible, tubular casing or jacket of theclass adapted to be readily applied .to cores of different sizes andcharacters, and the invention has for its object to provide such acasing or jacket which is formed of rubber tubing or the like and splitlengthwise, its edges being possessed of a strong, inherent, inwardlycoiling or rolling, and gripping tendency, said jacket being adapted toaccommodate itself to cores of different diameters.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the ap ended claims.

n the accompanying drawings:

Figure l is a perspective view showing a section of my improved tubingcoiled upon iself. illustrating its inherent coiling or rollingtendency.

Figure 2 is a perspective view illustrating a length of my improvedtubular casing as applied to a wire or other cylindrical core.

Figure 3 is a pers ective view illustrating a section of my exible,tubular casing as applied to a section of tubing for the purpose ofstiffening the same; also illus trating the edges of the casing asoverla ping.

t is found in practice that the cord of a telephone receiver oftenbecomes kinked, twisted or snarled causin much annoyance to the user, toobviate which a section of my flexible jacket may be opened uplengthwise and slipped over a cord which will at once straighten thekinks and the twisting.

Then again the discharge tube of-a fountain syringe oftenkinks and shutsoff the flow of water. To obviate this annoyance a section of the jacketmay be readily applied to the affected portion whereby the bindingaction of the tubular jacket forces the flattened ortion ofthewater-tube back to its norma shape permitting the free flow of watertherethrough.

Also as a protecting covering for electric wires, particularly shortsections of wire, which would ordinarily'have to be taped, it isonlynecessary to open up the tubing and slip it into place over the.wire, which will effectually insulate the wires and the job is donemuch quicker 'and presents a much neater appearance than when wound withthe usual electric tape.

The following is a detailed description of one construction of flexibletubing by which these and other similar results may be accomplished Myimproved tubular jacket is preferably I constructed of rubber orrubber-compoun or other suitable material molded or otherwise formedinto substantially tubular shape and split longitudinally as at 10, itsedges 11 being so constructed that they possess a strong,inwardly-rolling or curling tendency, as illustrated in Figure 1, tonormally reduce the size of the tubing so that the same will accommodateitself to fit and grip cores of different diameters. In other words thepiece of tubing as illustrated in Figure 2, is shown as being applied toa core such as a piece of wire 12, the edges 11 and 13 being drawn apartto unfold the tube lengthwisepermitting it .to be readily passed onto acore and upon being released the ed es of the tube instantly contractand fit tightly and hug the core gripping the same to hold the jacketfirmly in any set position thereon.

In some cases where the core is not large enough to expand the tube toits maximum capacity the edges 11 and 13 will overla' each other, asillustrated in Figure 3 an still grip and bind the core.

In some instances the outer surface of the jacket may be corrugated torender the same more attractive inappearance and also to provide abetter gripping surface on the tube to be engaged by the hand of theoperator.

My improved flexible tubular jacket or covering is ada ted for use oncores of grip and hug the same and .perform its functions of preventingthe twist, while another section of the same piece of tubing may beapplied to the collapsed discharge pipe of a syringe, its action beingto remove the kinks and cause this pipe to function properly, alsoanother section of the same length of j acketing may be applied toelectric wires such for instance as those on an automobile, which wouldotherwise have to be Wrapped with electric tape.

Its inherent coiling or rolling action remders it possible to apply thejacket to cores of widely different sizes instead of being obliged tohave a special size for each size of core to which it is to be applied.

The device has many practical usages and by its construction it may bereadily applied to cores of different characters and perform a coveringor jacketing eflect thereon.

I claim:

1. A tubular casing comprisingalength of flexible non-metallic tubingsplit lengthways to be readily applied to a core and having an inherentinwardly coiling or rolling action to grip and bind cores of difi'erentdi-,

ameters to which it may be applied without the use of other bindingmembers.

2. A tubular casingcomprisin a length of flexible non-metallic tubingspit lengthwise to be readily applied to a core, the edge of the tubehaving an inherent inwardly coiling or rolling action, adapted toautomatically grip, adhere to and support cores of different diameterswithout other binding members.

3. A tubular casing comprising a length of flexible non-metallic tubingsplit lengthwise to be readily applied to a core and having an inherentinwardly coiling or rolling action to grip and bind cores of dif ferentdiameters to which it may be applied \vihout the use of other bindingmembers, the outer surface of said tubing being corrugated. i

In testimony ture.
